The main purpose of the water cycle is to recycle and distribute water throughout the Earth's systems. This continuous process involves the evaporation of water from surfaces like oceans, lakes, and rivers, which then condenses into clouds as it cools. Eventually, this water returns to the surface as precipitation in various forms, including rain or snow. The water cycle is crucial for maintaining ecosystems, supporting plant and animal life, and regulating climate. Moreover, it plays a significant role in replenishing groundwater supplies and providing freshwater resources essential for human consumption and agriculture.
